: Super funny, improved controls, stealth play is light and welcomed, lots of replay value, some really cool weapons, amazing graphics and voice acting The Bad
: No multiplayer, Ratchet's sections are repetitive, the key mini-game is lame, very short
A lot of people hated Size Matters due to the fact that it had poor controls, and felt more like a console port. SAC was made from the ground up and feels more portable friendly. You play the main story as Clank who is a umm...secret agent and has to stop the thief of the Eye of Infinity which will destroy the entire galaxy.
Throughout the game you use stealth by sneaking up behind enemies, pressing square, and executing a series of buttons before the timer runs out. This is very refreshing and never really gets boring. What I really liked about the stealth is that it's not demanding and doesn't have you hiding in shadows or keeping your noise down. You can just run up behind enemies and even their line of sight is fairly short. You can use some very clever weapons such as the Tangle Carnation which releases pods that eat enemies, the holo-monacle which lest you disguise yourself as the enemy, and even cufflink bombs. You also perform some well designed platforming, solve some simple puzzles with your special key (it's probably the worst mini-game in the whole game). While you prance around as Clank you can use your Gadgebots to unlock doors through a series of puzzles you have to solve and these are super fun and addictive.
Clank also has some mini-games of his own such as snowboarding, and a series of driving mini-games where you have to avoid obstacles. When you finish the mini-game you can play more of the same type to get more bolts (money) like in all the other R&C games. Some other mini-games have you doing timed button presses which really keeps things from getting stiff. Aside from the Clank sections you can play as Ratchet in jail fending off his fellow prison mates. These are actually very repetitive and are the same arena games seen in other R&C games. Quark's games are the funniest and are really weird. You have Quark saving space nuns, saving fishmen from killer cacti, and even singing about his left butt cheek. With all of this combined you can unlock skill points and find Titanium bolts to unlock more skins.
I never really found this game boring and it has a lot of replay value for R&C fans. There is no multiplayer this time around, but it's not really missed. The game looks amazing and is probably in the top five best looking PSP games out there right now. If you want a super funny, fun, and unique single player game on the PSP pick this up.
